Occupancy sensing

Occupancy sensing

Motion sensors that control lights according to space occupancy. Passive infrared sensors are the most common. Ultrasonic sensors work better in places with partitions. Sensors have sensitivity and time-out adjustments to fine-tune their use. Wall box sensors with internal switches or dimmers are used for small rooms. Multiple sensors are needed for larger spaces. Energy credit for their use are substantial, and the payback is short for retrofit applications.

Eaton will showcase its award-winning WaveStream LED technology and AccuLED Optics system, as well as its Integrated Sensor Control System, which allows for occupancy sensing, turning light off when the spaces are unoccupied; daylight harvesting that reduces light level when natural light enters the space; and dimming capabilities, allowing users to set maximum light levels lower than full brightness.
The growth in the real estate sector is another major driver for the occupancy sensing market, as the number of construction projects are increasing.
The Blackfin Low Power Imaging Platform (BLIP) leverages the ADSP-BF707 Blackfin processor as well as Analog Devices' optimized software libraries for video occupancy sensing.
The cost of the daylight sensor is generally the same cost as the occupancy sensor, and proper daylighting often provides a similar percentage energy reduction, but a considerably larger percentage peak power reduction than occupancy sensing.
Each UP32x supports occupancy sensing, two (2) digital inputs for condensate switch, dirty filter or other fault condition, and an advanced remote sensor bus.
Their experimental studies not only demonstrate the feasibility of IT based implicit occupancy sensing but also reveal that the IT based implicit methods are able to detect beyond simple occupant counts: they are also able to detect occupants' location and activities.
The problem can disable the front airbags, seatbelt pretensioners and the Automatic Occupancy Sensing module.
Bruce Nordman of the Lawrence Berkeley National Laboratory, plus Ken Christensen of the Department of Computer Science and Engineering at the University of South Florida, and other colleagues from those institutions and the University of Puerto Rico at Arecibo, explain how implicit occupancy sensing can be undertaken using existing IT infrastructure.
Lastly, Control Scenario 6, "Wireless Full Dimming," provided the most robust control system, with full daylight dimming, high-end trim dimming, lumen maintenance dimming, and occupancy sensing in all major spaces.
These systems do have a higher first cost than occupancy sensing or timeclock control but can provide greater or additional ongoing benefits.
This equipment is fitted in addition to the standard package of five-speed manual gearbox, driver's seat electric height adjustment, anti-lock brakes and traction control as well as front and side, driver and passenger airbags and occupancy sensing.
